Planning Instructions Fire alarm system EBL512 G3, United version 2.7.x
Cable types
A fire alarm installation is a safety installation and it is important that
the cables used are of correct types and according to national
regulations, e.g. regarding cable colour, method of mounting, etc. Fire
alarm cables should, when possible, be installed as far away from
other cables as possible, in order to avoid disturbances from these.
The maximum cable length is depending on the cable type (area,
twisted / not twisted pairs, screen / no screen), the units' current
consumption, etc.
TLON Network cables
An unshielded Belden cable with twisted pair should be used, e.g.
85102 or 8471.
See also separate TLON Technical description.
COM loop cables
Loop topology is used for highest safety, i.e. the cable, connected in
the control unit, returns back to the control unit. In case of a break on
the loop, communication in two directions starts.
See dwg. 512 G3 – 25, – 31 and – 41.
Cable length is depending on the type and number of loop units, etc.
See chapter "COM loop cable length", page 145 and dwg. 512 G3 -
41.
